@edgeandnode/graph-auth-kit

Authentication Kit for connecting The Graph apps/dapps to a wallet.

Relies on/requires wagmi + viem for allowing users to connect their wallets and interact with the connected auth state context.

Exposes a simple useGraphAuthKit hook that lets the app open the connect modal, letting users connect to their wallet of choice (one of: injected/MetaMask, coinbase, WalletConnect, Safe). See integration example below.

Install

Currently, graph-auth-kit has a lot of peer deps needed to interact with the library. But this may change after testing. At the very least, wagmi, viem, @tanstack/react-query will be needed.

``bash


with bun

bun add @edgeandnode/graph-auth-kit \
@edgeandnode/common \
@edgeandnode/gds \
@edgeandnode/go \

Usage

Properties:

- config -> [REQUIRED]. The instantiated wagmi config instance.
- queryClient -> [OPTIONAL]. The GraphAuthKitProvider renders a QueryClientProvider instance. Pass in an instantiated QueryClient to use, otherwise, GraphAuthKit will instantiate its own.
- infuraKey -> [REQUIRED]
- gatewayApiKey -> [OPTIONAL]. A The Graph Gateway API key used to query Subgraphs published on the Graph Network. Used for ENS name resolution

$3

- Setup the GraphAuthKitProvider.
- Note you do not need to add the ConnectModal component, the GraphAuthKitProvider renders it for us
- Note you do not need to add the QueryClientProvider as GraphAuthKitProvider instantiates and renders it
- you can pass a QueryClient instance to the GraphAuthKitProvider, otherwise, it will instantiate its own

`tsx
// _app.tsx

import { QueryClient } from '@tanstack/react-query'

- Usage in a component

`tsx
// components/Layout.tsx

import { ReactNode } from 'react'
import { useAccountEffect, useEnsName } from 'wagmi'

import { Layout as GDSLayout, UserProfile } from '@edgeandnode/gds'
import { GlobalFooter, GlobalHeader, NPSForm } from '@edgeandnode/go'
import { L1Chain, useGraphAuthKitConnector, useGraphAuthKit, useGraphAuthKitAccount } from '@edgeandnode/graph-auth-kit/hooks'

import { NavDropDownMenu } from './NavDropDownMenu'

export function Layout({ children }: Readonly<{ children: ReactNode }>) {
const authkit = useGraphAuthKit()
const { address } = useGraphAuthKitAccount()
const { data: ens } = useEnsName({ address, blockTag: 'latest', chainId: L1Chain.id })
const connector = useGraphAuthKitConnector()

const walletConnected = Boolean(address)

useAccountEffect({
onConnect(data) {
console.log('user connected wallet', {data})
},
onDisconnect() {
console.log('user disconnected wallet')
},
})

return (
header={
activeProduct="EXPLORER"
basePath="/explorer"
showSupportButton={walletConnected}
rigtContent={(defaultContent) => (
<>
{!walletConnected ?
authkit.openConnectModal()} />
) : (
ethereumAccount={address}
graphAccount={...}
ens={ens}
profileUrl={/profile/${address}?view=Overview}
profileUrlAs={/profile/${address}?view=Overview}
onConnect={() => authkit.openConnectModal()}
onDisconnect={() => authkit.disconnect()}
userDropDownMenu={}
accountTag={connector === 'safe' ? 'multisig' : undefined}
/>
)}

)}
/>
}
footer={
<>



}
>
{children}

)
}
`

Hooks

- useGraphAuthKitAccount -> This is an override of the wagmi useAccount hook. The reason is, if the user connects with a multisig, the wagmi context is connected with the user-selected EoA, so all of the wagmi context hooks reference this EoA and not the Safe. This returns the wagmi UseAccountReturnType but the address and addresses values include the entered Safe address. It also adds an eoa property that is the connected EoA address.
- useGraphAuthKitConnector -> The user selected wallet/connector option.
- useClientToEthersSigner -> Returns the ethers@5.x.x JsonRpcSigner or SafeEthersSigner if the user is connected via a multisig
- useAuthAccount -> similar to the useGraphAuthKitAccount but requires the user to be authenticated and throws an error if not
- useGraphAuthKitAccountEffect -> Override of the wagmi useAccountEffect hook that listens to account changes and the _enteredMultisigInfo on the inner context instance. If the account data changes, emits a onConnect or onDisconnect event, but in the onConnect also checks the useGraphAuthKitInnerContext()._enteredMultisigInfo value and if the user has connected via a multisig, returns the mutlsig as the address value and the connected EoA as the eoa value.
- useGraphAuthKitWalletClient -> Override of the wagmi useWalletClient hook that returns the extended Safe viem actions if the user is connected to a multisig.
- useGraphAuthKitWriteContract -> Override of the wagmi useWriteContract hook that creates the transaction on the Safe if the user is connected via multisig; otherwise, returns the useWriteContract mutation hook.

Components

- Connected -> renders the passed in children _only if_ the user is connected.

`tsx
import { Connected } from '@edgeandnode/graph-auth-kit'

export function ShowMeConnected() {
return {(account) =>

}
}
`

- Disconnected -> renders the passed in children _only if_ the user id disconnected. Useful for rendering components like a "Connect Wallet" CTA that should only render if the user is _not_ authenticated.

`tsx
import { ExperimentalButton as Button } from '@edgeandnode/gds'
import { Disconnected, useGraphAuthKit } from '@edgeandnode/graph-auth-kit'

export function ShowMeDisconnected() {
const authkit = useGraphAuthKit()

return (

authkit.openConnectModal()}>
Connect Wallet


)
}
`

- SwitchChain -> Similar to the SwitchNetwork component from GDS, but uses the wagmi useSwitchChain hook.

`tsx
import { ExperimentalButton as Button } from '@edgeandnode/gds'
import { L2Chain, SwitchChain } from '@edgeandnode/graph-auth-kit'

export function LetMeSwitchChain() {
return
}
`
